This study was conducted to determine adult population change, infestation and damage rate of Prays oleae Bern. (Lepidoptera: Praydidae) generations which are in leaves, flowers and fruits. Studies were conducted in 30 olive orchards in the Dara village and Derik district of Mardin province in 2016–2017 in Turkey. Samples were collected from three different orchards containing at least 30–40 olive trees. Samplings were done weekly by pheromone traps, visual inspection and shoot methods. As a result of the study, it was determined that Olive moth was distributed in the village of Dara and districts of Derik and Nusaybin, but was not distributed in districts of Kızıltepe of Mardin province. The general infestation ratio of the pest was 73.33% and olive moth had three peak points in a year, such as in early May, second week of June and in early October in the Mardin province. It was found that it had three generations in a year and adults of the pest appeared from April to November in Mardin province. It was also determined that the damage rate of the pest was between 12–21% in leaf generations, 2–5% in flower generations, and between 0.8–5% in fruit generations based on the years and the orchards.

确定造成果园损坏的橄榄蛾,油菜(伯纳德)(鳞翅目:Praydidae)的分布,种群变化,侵染和破坏情况

进行这项研究以确定成年人口的变化,侵扰和油菜的损坏率伯尔尼 (鳞翅目:Praydidae)世代存在于叶子,花朵和果实中。研究于2016–2017年在土耳其马尔丁省Dara村和Derik区的30个橄榄园中进行。从三个至少包含30–40棵橄榄树的不同果园中收集样品。每周通过信息素捕获器,目视检查和射击方法进行采样。研究的结果是,确定橄榄飞蛾分布在达拉村以及Derik和Nusaybin地区,但没有分布在马尔丁省Kızıltepe地区。害虫的总体侵染率为73.33%,橄榄蛾在一年中有三个高峰,例如在马尔丁省的5月初,6月的第二周和10月初。据发现,一年中有三代,害虫成虫从四月到十一月出现在马尔丁省。还根据年份和果园确定,害虫的危害率在叶片世代中为12–21%,在花朵世代中为2–5%,在水果世代中为0.8–5%。
